Cataracts

What is a cataract?

A cataract is a clouding or opacity of the crystalline lens, the human eye's natural lens whose purpose is to ensure clear vision.

It generally develops over time, meaning that cataracts are a vision problem that the entire population is going to suffer at some point. It is not a disease, but simply the ageing of the eye.

Symptoms

Reduced visual acuity is one of the most evident and typical symptoms in people who are developing a cataract.

Depending on the size and location of the areas of opacity of the lens, a person may or may not realise that they are developing a cataract. If it is located on the outer edge of the lens, the person's vision will not be affected, but if the opacity is located near the centre of the lens, it generally interferes with vision./p>

The eyes may be more sensitive to light, making driving difficult. Cataracts also alter colour perception. And in many cases they can cause diplopia - double vision in the eye that is affected by the cataract.
